Rotary Flux Injector (RFI)
We adopt Rotary Flux Injector (RFI) manufactured by
STAS (Canada) to refine molten aluminum. In order to achieve the
optimum mixture, flux and inert gas are injected into molten aluminum
through RFI's high velocity rotating graphite rotors. Temperature and
chemical composition can be uniformed; meanwhile, volume of alkaline
and impurities are reduced and cleanliness of molten aluminum
increased.

Electromagnetic Stirring (EMS)
In the bottom of furnace, we installed Electromagnetic
Stirring (EMS) manufactured by SHINKO (Japan). Without contacting the
metal, this equipment stirs the metal within the furnace by
electromagnetism, speeding stirring to achieve the goal of even
temperature and chemical composition. Compared with conventional
equipment, EMS shows better efficiency on high-strength alloys.

Double Filtration System &
Ceramic Foam Filter To ensure quality standard of our billet, patented
double filtration system with the first layer of 26” Pore Size
(40~50PPI) and second layer of 23” Pore Size (60~70PPI) and LIG
preheat lid manufactured by Selee Corporation USA, are equipped in our
production line. Double filtration system can effectively remove
impurity particles and further ensure final product quality.

Automatic & Continuous
Homogenization Plant The continuous homogenization furnace imported from
Austria is a type of horizontal billet feeding. It handles billets one
by one for providing more uniform treatment than batch type unit. The
whole homogenization process is monitored by computer programs, which
avoids any personal error. Tzan Wei’s furnace is the 1st unit
installed in Taiwan.

Batch-Type Furnace & Cooling
Furnace.To comply with the homogenization requirements of
high-strength alloys, Tzan Wei installed four sets of 20-ton
batch-type furnaces and two sets of cooling furnaces. Equipped with
high efficiency thermal circulation fan manufactured by I.G.E. (USA),
the PLC system precisely controls the temperature and
increases/decreases temperature in different stages based on alloy
type. All are for best homogenization quality of aluminum billets. In
cooling furnace, there are 12 fans for controlling cooling rate of
homogenized billet. There is temperature measure for calculating the
cooling rate too.
